Beit known that I. ALBERT, C. *HESSEL,

a citizen ofthe United States,.residing inv the city, county, and Stateof New York,

have invented certain new and useful Improvements in Conduits, of,which'the following, taken in connection, with the accompanying sheetsof drawings,is a full, clear, and concise description'thereof. Y

My present inventionrelates primarily to a conduit construction fortheaccommodation of steam conveying pipes and other pipes. j i

Among the objects of my invention is to provide a flexible, compositesystem for service pipes in general, that is to say, a system in whichprovision is initially made for the accommodation of steam, gas, oil andwater pipes, and where desirable pipes for sewerage, so. that by asingle installation at a single initial expenditure, an entire serviceeventually may be taken jcare of. I

A further object of my invention is to provide a new and novel trenchconstruction for accommodating the service pipes.

A further object of my invention is to provide specifically new andnovel means. for supporting steam conveying pipes within the trench'. w'1;

Another object of: myinvention is to provide a new, and novelform ofexpansion joint between abutting ends of the trench sections, a

A still further object of my invention is to provide a new and novelform of interior and exterior drainage system for a trenc of my improvedconstruction.

Further objects will make themselves manifest upon a reading andunderstanding of the following specification and accompanying drawings,in which I have set forth preferable embodiments of my invention. i

Referring to the drawings: Figure 1 is a vertical cross-sectional viewof a system involving certain of thefeaturesof myinvention." Fig. 2 is asimilar view of a modification thereof. Fig. 3 is a similar view of afragmentary portion thereof'jjillustrating more particularly thedrainage features thereof.

ofa trench, illustrating an expansionjoint conforming to certainfeatures of my invention. c g

, In conduit construction.generally, it is extremely advantageous toprovide a substantial supporting foundation. for the con duit andcontained steam conveying pipes. It is one ofthe principal objects of myinvention to provide such adequate? support for the steam conveyingpipes while at the same time avoiding the use of the usual well-knowncylindrical conduits; fThis I accomplish by formingwhat Ifterm herein amonolithic trench 1, having the bottom and sides formed integral with aremovable sectional top 2, preferably 1 of ,concrete slab construction.-The concretev trench is built at the'point of installation,*while thetop sections 2 may have previously been; fonned and transported tothepoint of use. jWhere found desirable the trench may be j reinforced asat 2'. (Fig.2). jAfter thetop sections 2 are placed,' thefp,oi ntoffjointure is covered with cementa's at--2"-.: The steam conveyingpipes 3 are supported on suitable rollers4, which in turn are supportedby rods 5, the ends of thelatter being positioned' in the sides of/theconcrete trench when being built. In this manner the. necessary adequatesupport. is qgiven to the steam pipes. Where necessary,. or .where founddesirable, the rods 5 maybe additionally supported by suchsuitablereinforcing means as shown at 7, (Fig.1) where aperfo; ratedplateis embedded in the concrete wall accommodationof the 0 of thetrench, said plate being provided with pipes, such as gas and water-andpipes for 7' the I electric conductors. [Certain of, these pipes areinstalled whenthe trench is built,

the same being embedded within the bottom or side walls thereof, while.other of the pipes such as the water and gas pipes may be installed atsome future or later-time and these are'positioned preferably-within theinterior orcavity ofthe trench. In Fig. 1,

I have shown gas andwater pipes-resting .105

upon the bottom of thetrench, and the pipes for the accommodation of theelectrical conductors positioned within thebody of the bottom of theconcrete trench,'whi1e in Fig.

2,1 show these 'latter pipes positioned withgun cylindrical openingsthrough the concrete 'for the accommodation ofthe insulated conductors.

In order to provlde forthe 1nter1or dramage of seepage water Or water ofcondensation, and also the drainage of the immediate exterior of thetrench, I provide a suitable system-0f drainage such as that shown inFig. 3 in which pipes 8 are arranged exterior ofthe trench and a pipe 9leading from the interior thereof, preferably at its lower inclined end,all of which pipes communicate with a common outlet 10 discharging atany desirable point.

In order to afford an adequate foundation and support for'the drainpipes S, I preferably forinlaterally extending flanges 11 to the base ofthe trench, these being of integral construction therewith.

To increase the insulating properties of the system, I provide, wheredesirable, a

containing tube 12, made of cast asbestos, cork or'other suitableinsulating material, reinforced by another surrounding containing tube13 (see Fig. 2). The containing tube 12 is sectional in form and therods 5 are positioned between the ends of adjacent sections, as shown inFig. 5, in which are illustrated thelower halves of two adjacentsections of the containing tube. Between the sections a filler ofplastic cement is provided to form a seal. The containing tube at thepoint of uncture between the sections is supportedby a-block of concrete5 while similar blocks 5 may be provided to space the containing tubefrom the sides of the trench (seeFig. 2). Where these containers areused it will be observed that a high degree of insulation is provided asthey serve to maintain a dead air space between the same and the steamconveying pipes. If

a desirable, these spaces may be filled with any fibrous insulatingfiller. As an alternative construction, I may make the con taining tubeoftwo-part metal construction as shown at 14 (see Fig. 4), these partsbeing provided with laterally extending flanges or ears 15, which may bebolted to projecting coincident flanges or ears '16, embedded in theside walls of the trench 1.

Accordin'gto another phase of my invention, I providea new and improvedformof sectional topforthe concrete trench (see Fig. This top isreenforced and made thicker at the longitudinal central zone crete topslabs.

thereof, the outer curvature being concentric with the centrallongitudinal axis of the trench. This form possesses a maximum abilityfor resisting stresses imposed thereon by the covering earth.

In order to take care of expansion and contraction, I provide a novelform of joint between adjacent ends of the trench so formed for thispurpose. This I have shown in detail in Fig. 5 in which the top sectionsare provided with angular sheet metal members 17 and 18 11 ring oneextremity embedded within and supported by the con- These members arepreferably made of springing material, the member '17bein )rovidcd withan an ular extension 19 which extends downwardly below the upper edge ofthe member 18, so as to make a desirable form of joint to prevent waterfrom seeping past. This joint is further protected by a filler 20 ofcementitious material. In the event, however, of seepage water passingthe joint thus formed, I provide the trough 21, which is supported bysuitable lugs 22 cast integral with the top section. This trough 21 isarranged'so that its ends will discharge within the trench along thewalls thereof, so that any seepage water entering may pass out throughthe drain 9. I may, when desirable, make the members 17 and 18 ofintegral construction, as at 23, the flexibility of the material beingsufficient to allow for expansion or contraction as the case might be.

It will thus be observed that in a system constructed in accordance withthe abovedescribed principles, the possibility of seepage water comingin contact with insulating material, is removed. This is very importantas, in ordinary systems, as now employed, where seepage does occur, ithas disastrous results and requires usually an expenditure of a. greatdeal of money, labor and material to locate and correct the same.

In my system many cubic inches of water per lineal foot of conduit canflow con tinuously within the concrete trench. and yet do no harm, thesame discharging from the trench at a desirable point, preferably thelower end of the trench.

In addition to this, in my system I make provision for taking care ofthe seepage water that may enter at the sides and exterior of-thetrench, where the ditch is filled with cindcrs, this water preferablybeing dis charged also at the lower on d of the system. The exteriordrainpipcs are, in my system, provided with a very substantialfoundation which entails very slight additional expense because it is,in its preferable form. con structed as an integral part of the concretetrench itself.

Of equal importance to the above advantages is the flexibility of thesystem described, that is to say, the facility with which I to steamconveying, may be taken care of at practically no additional cost exceptfor the necessary and required material.

It will be understood that in a long run of steam work where no manholes occur, it will become necessary to establish electric man holes-to facilitate the. installation of the electric cables. Where steam'manholes do occur, a combinationman hole can be con structed, and the wallsandfloor of the. steam man hole can be chased to allow the electriccablesto be entirely concealed.

lVhile I have illustrated and described certain preferred embodimentsofmy inven tion, I do so by way of example only, as- -changes may bemade in the structural details thereof without departing from the spiritand scope of my invention, as defined by the following claims.
